2022 Map of Blencoe
USGS Topo · Published 2022About this map
Blencoe and the southern outskirts of Onawa define the settlement pattern of this Monona County landscape, where the rectilinear grid of the Public Land Survey System is deeply etched into the Missouri River floodplain. The area's agricultural history is written in its complex drainage network, featuring significant engineering works like Fletcher Ditch, Sherman Ditch, and McNeil Ditch that transformed the prairie into productive farmland. These waterways, along with remnants like Guard Lake and the Oliver Lake Ditch, reflect a long-term effort to manage the local hydrology.
